Generator paralleling is a frequent and essential operation in the power system. If the frequency error is too great, the oncoming generator could slip a pole, causing damage to the machine. Therefore, the precision frequency measurement of the generator and the power system is one of important conditions to ensure that the automatic quasi-synchronizer can operate accurately. A new method of frequency...
According to the traditional p-q theory had many problems, the improved p-q method is studied in this paper. The distorted voltage is transformed to ideal voltage through the space vector. Harmonic suppression and reactive power compensation are finished under the distorted voltage by use of three-phase four-wire four-leg active filter. Comparing to the traditional p-q theory, the simulation results...
